Basic knowledge of asphalt mixing plant bag

Bag-type dust collector of asphalt mixing plant particles of dust control device of choice. The most typical asphalt equipment bag is closed by a steel shell containing high efficiency dust filter bag, and accompanied by ash conveying system and fan and electric control shall constitute a complete set of asphalt mixing plant dust removal system. asphalt mixing plant bag's basic technique is simple. Principle is mainly asphalt production equipment from the dust concentration in the exhaust gas prior to entering the atmosphere through the filter fabric filter dust bag inside the box, dust cannot be accumulated through efficient dust bag out of the bag.

Asphalt mixing plant flue gas treatment process

1. the drum mixer or dryer exhaust dust concentration in the exhaust gas through a pipe into a filter (inertial separator or cyclone), by a dust-removal of coarse dust.

2. adoption of a dust collector dust concentration in the exhaust, air intake slowly into the bag, the proliferation of air fill the filtering Chamber.

3. the dust concentration in the air through fan negative pressure through dust bag, dust and the air flow through the filter bag dust accumulates in the outside of the filter bag.

4. with the continued accumulation of dust on the surface of the filter bag, when the programmed filter resistance value, the cleaning system of periodic high pressure air from the top into the dust bag, filter bag this violent shaking, dust from falling into the hopper, excluded by ash bucket at the bottom of the spiral conveyor.

5. through a bag filter clean air through fan vented into the atmosphere.

Asphalt mixing plant bag house filter materials choice

asphalt mixing plant bag can not only meet the most stringent emission standards of 2015 the latest environmental law. Bag also has a very good economic advantages, asphalt mixing plant through the recycling of bag house dust can be reused, which is to protect the environment and prevent the waste of raw materials.
